Visual snow syndrome (VSS) is an uncommon neurological condition in which the primary symptom is that affected individuals see persistent flickering white, black, transparent, or colored dots across the whole visual field. [7] [4] Other common symptoms are palinopsia, enhanced entoptic phenomena, photophobia, and tension headaches.
In dichoptic visual masking, the target is presented to one eye and the mask to the other, whereas in monoptic visual masking, both eyes are presented with the target and the mask. It was found that the masking effect was just as strong in dichoptic as it was in monoptic masking, and that it showed the same timing characteristics. [6] [7] [8]
Saccadic masking, also known as (visual) saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
Eye movements are important behaviors for locating and tracking objects in the visual world. Two of the major types of eye movements are saccades and smooth pursuit. Saccades are very rapid and precise eye movements between two positions, and are important in establishing fixation. Smooth pursuit on the other hand, allows the viewer to track a ...
Binocular rivalry was discovered by Porta. [6] Porta put one book in front of one eye, and another in front of the other. He reported that he could read from one book at a time and that changing from one to the other required withdrawing the "visual virtue" from one eye and moving it to the other.

McCloud argues that characters with simple but recognizable designs, which he terms "iconic" characters, allow readers to project themselves into the story by using the ...
To observe flash suppression, a small image is first presented to one eye for about a second while a blank field is presented to the other eye. Then a different, small image is abruptly shown, flashed, to the other, second eye at the location corresponding to the image to the first eye. The image to the first eye disappears, even though it is ...

In psychology and sociology, masking, also known as social camouflaging, is a defensive behavior in which an individual conceals their natural personality or behavior in response to social pressure, abuse, or harassment.
